Though Murphy was famous for her acting, her musical résumé is pretty impressive, too.

Just three years ago, she and Paul Oakenfeld hit the charts with the club song "Faster Kill Pussycat." She also sang covers of Queen's "Somebody to Love" and "Earth Wind & Fire's "Boogie Wonderland" in Happy Feet, the 2006 animated flick costarring Nicole Kidman, Hugh Jackman, Robin Williams and Elijah Wood.

Sources tell me that music executives have already started to do some digging to find any unreleased songs Murphy may have recorded over the years...

"Obviously this isn't a Michael Jackson thing, but people are definitely interested in Brittany and her story," one executive tells me. "Depending on what she may have recorded and what kind of quality it is, she could end up having a hit song or two."

Murphy's musical aspirations date back to the early '90s, when she fronted Blessed Soul, a band she formed with fellow actor, Six Feet Under and 24 star Eric Balfour.
